RESUMO
Introduction: There are disparities in multiple aspects of pediatric asthma care; however, prehospital care disparities are largely undescribed. This study's objective was to examine racial and geographic disparities in emergency medical services (EMS) medication administration to pediatric patients with asthma. Methods: This is a substudy of the Early Administration of Steroids in the Ambulance Setting: An Observational Design Trial, which includes data from pediatric asthma patients ages 2-18 years. We examined rates of EMS administration of systemic corticosteroids and inhaled bronchodilators by patient race. We geocoded EMS scene addresses, characterized the locations' neighborhood-based conditions and resources relevant to children using the Child Opportunity Index (COI) 2.0, and analyzed associations between EMS scene address COI with medications administered by EMS. Results: A total of 765 patients had available racial data and 825 had scene addresses that were geocoded to a COI. EMS administered at least 1 bronchodilator to 84.7% (n = 492) of non-White patients and 83.2% of White patients (n = 153), P = 0.6. EMS administered a systemic corticosteroid to 19.4% (n = 113) of non-White patients and 20.1% (n = 37) of White patients, P = 0.8. There was a significant difference in bronchodilator administration between COI categories of low/very low versus moderate/high/very high (85.0%, n = 485 vs. 75.9%, n = 192, respectively, P = 0.003). Conclusions: There were no racial differences in EMS administration of medications to pediatric asthma patients. However, there were significantly higher rates of EMS bronchodilator administration for encounters in low/very low COIs. That latter finding may reflect inequities in asthma exacerbation severity for patients living in disadvantaged areas.
RESUMO
INTRODUCTION: Pediatric asthma exacerbations are a common cause of emergency medical services (EMS) encounters. Bronchodilators and systemic corticosteroids are mainstays of asthma exacerbation therapy, yet data on the efficacy of EMS administration of systemic corticosteroids are mixed. This study's objective was to assess the association between EMS administration of systemic corticosteroids to pediatric asthma patients on hospital admission rates based on asthma exacerbation severity and EMS transport intervals. METHODS: This is a sub-analysis of the Early Administration of Steroids in the Ambulance Setting: An Observational Design Trial (EASI AS ODT). EASI AS ODT is a non-randomized, stepped wedge, observational study examining outcomes one year before and one year after seven EMS agencies incorporated an oral systemic corticosteroid option into their protocols for the treatment of pediatric asthma exacerbations. We included EMS encounters for patients ages 2-18 years confirmed by manual chart review to have asthma exacerbations. We compared hospital admission rates across asthma exacerbation severities and EMS transport intervals using univariate analyses. We geocoded patients and created maps to visualize the general trends of patient characteristics. RESULTS: A total of 841 pediatric asthma patients met inclusion criteria. While most patients were administered inhaled bronchodilators by EMS (82.3%), only 21% received systemic corticosteroids, and only 19% received both inhaled bronchodilators and systemic corticosteroids. Overall, there was no significant difference in hospitalization rates between patients who did and did not receive systemic corticosteroids from EMS (33% vs. 32%, p = 0.78). However, although not statistically significant, for patients who received systemic corticosteroids from EMS, there was an 11% decrease in hospitalizations for mild exacerbation patients and a 16% decrease in hospitalizations for patients with EMS transport intervals greater than 40 min. CONCLUSION: In this study, systemic corticosteroids were not associated with a decrease in hospitalizations of pediatric patients with asthma overall. However, while limited by small sample size and lack of statistical significance, our results suggest there may be a benefit in certain subgroups, particularly patients with mild exacerbations and those with transport intervals longer than 40 min. Given the heterogeneity of EMS agencies, EMS agencies should consider local operational and pediatric patient characteristics when developing standard operating protocols for pediatric asthma.

INTRODUCTION: Pediatric hospital care is becoming increasingly regionalized, with fewer facilities providing inpatient care for common conditions such as asthma. That trend has major implications for emergency medical services (EMS) medical care and operations because EMS historically transports patients to the closest facility. This study describes EMS transport patterns of pediatric asthma patients in greater depth, including an analysis of facility bypass rates and the association of bypass with demographics and clinical outcomes. METHODS: This was a retrospective study of pediatric asthma patients ages 2-18 years transported by Lee County, FL EMS between March 1, 2018 - December 31, 2019. A priori, we defined bypass as greater than five minutes extra transport time. We performed geospatial analysis and mapping of EMS pediatric asthma encounters. We used the Pediatric Destination Tree (PDTree) project's tiered approach to characterize receiving hospital facility pediatric capability. We analyzed incidence and characteristics of bypass, and bypass and non-bypass patient characteristics including demographics, emergency department (ED) clinical outcomes, and socioeconomic disadvantage (SED). RESULTS: From the study period, there were a total of 262 encounters meeting inclusion criteria, 254 (96.9%) of which could be geocoded to EMS incident and destination locations. Most encounters (72.8%) bypassed at least one facility, and the average number of facilities bypassed per encounter was 1.52. For all 185 bypass encounters, there was a median additional travel time of 13.5 minutes (interquartile range 7.5 - 17.5). Using the PDTree's classification of pediatric capability of destination facilities, 172 of the 185 bypasses (93%) went to a Level I facility. Bypass incidence varied significantly by age, but not by minority status, asthma severity, or by the area deprivation index of the patient's home address. Overall, the highest concentrations of EMS incidents tended to occur in areas of greater SED. With regard to ED outcomes, ED length of stay did not vary between bypass and non-bypass patients (P = 0.54), and neither did hospitalization (P = 0.80). CONCLUSION: We found high rates of bypass for pediatric EMS encounters for asthma exacerbations, and that bypass frequency was significantly higher in younger age groups. With national trends pointing toward increasing pediatric healthcare regionalization, bypass has significant implications for EMS operations.

OBJECTIVES: Little is known about emergency medical services' (EMS') management of pediatric asthma. This study's objective was to describe the demographic, clinical, and geographic characteristics of current EMS' management of pediatric asthma in the state with the fourth-largest pediatric population. METHODS: This was a retrospective observational study of EMS patients ages 2 to 18 years with an asthma exacerbation from 2011 to 2016. Patients from Florida's EMS Tracking and Reporting System were included if their EMS chief complaint indicated respiratory distress, if they received at least 1 albuterol treatment, and if they were transported to a hospital. RESULTS: A total of 11,226 patients met the inclusion criteria. The median age was 9 years, and 49% were African-American. Geospatial analysis revealed 4 rural counties with disproportionate numbers of African-American patients. In addition to albuterol, 37% of patients received ipratropium bromide and 9% received systemic corticosteroids. Adjusted logistic regression revealed that the strongest predictors of receiving systemic corticosteroids from EMS were intravenous access (odds ratio, 33.4; 95% confidence interval, 24.4-45.6) and intravenous magnesium sulfate administration (odds ratio, 5.0; 95% confidence interval, 3.4-7.3), indicating a more severe presentation. CONCLUSIONS: This statewide study demonstrated low rates of EMS administration of ipratropium bromide and systemic corticosteroids, both evidence-based treatments for asthma exacerbations. Targeted EMS education should attempt to increase utilization of both those medications. In addition, the feasibility and efficacy of EMS administration of oral systemic corticosteroids for children should be explored.

BACKGROUND: Pediatric asthma exacerbations are a frequent reason for emergency care. Early administration of oral systemic corticosteroids (OCS) in the emergency department (ED) decreases hospitalization rates and ED length-of-stay (LOS). However, it is unknown whether even earlier OCS administration by emergency medical services (EMS) in the prehospital setting further improves outcomes. PURPOSE: To describe the background and methods of a type 1 hybrid effectiveness-implementation trial of EMS-administered OCS for pediatric asthma patients incorporating a stepped wedge design and the RE-AIM framework. METHODS: The study employs a non-randomized stepped wedge design where multiple EMS agencies adopt OCS as a treatment for pediatric asthma exacerbations at varying times. This design accommodates ethical considerations of studying pediatric subjects in the prehospital setting where informed consent is not feasible. We will compare hospitalization rates, ED LOS, and short-term healthcare costs between pediatric asthma patients who do and do not receive OCS from EMS. Using geographic information systems (GIS), we will measure how differences in outcomes scale with increasing EMS transport time. We will use the RE-AIM framework to guide a mixed methods analysis of barriers and enablers to EMS administration of OCS for pediatric asthma patients, including quantitative measures of adoption and uptake and qualitative EMS provider focus group data. CONCLUSION: This trial will determine if earlier EMS administration of OCS to pediatric asthma patients decreases hospitalizations, ED LOS, and short-term healthcare costs, and if those outcomes scale with longer EMS transport times. We will identify barriers and enablers to implementing EMS-administered OCS for pediatric asthma patients.

Introduction: Deciding where to transport a patient is a key decision made by emergency medical services (EMS), particularly for children because pediatric hospital resources are regionalized. Since evidence-based guidelines for pediatric transport destinations are being developed, the purpose of this study was to use a large statewide EMS database to describe current patterns of EMS providers' transport destination decisions for pediatric patients.Methods: This is a retrospective study of pediatric transports from 2011-2016 in EMS Tracking and Reporting System (EMSTARS), Florida's statewide EMS database. We included patients greater than 1 day and less than or equal to 18 years who were primary EMS scene transports. Our primary outcome variable was 'reason for choosing destination.' We performed descriptive and comparative analysis between closest facility and all other 'reason for choosing destination' choices. We used geospatial analysis to examine destination choice in urban and rural counties.Results: Our final study sample was 446,274, and 48.2% of patients had closest facility as their 'reason for choosing destination.' The next largest category was patient/family choice (154,035 patients, 35.7%). Closest facility patients were older (median age 12 versus 10 years, p < 0.0001) and had shorter median EMS transport times (11.3 versus 15 minutes, p < 0.0001) compared to all other destination decisions. Notably, 60% of respiratory distress patients' and 44% of seizure patients' reason for choosing destination was something other than closest facility. Geospatial analysis revealed that fewer rural patients were documented as closest facility compared to urban (43.9% versus 47%, p < 0.0001). Correspondingly, more rural patients' destination decision was patient/family choice than urban patients (36.3% versus 34.3%, p < 0.0001).Conclusions: This large, statewide study describes EMS' reason for choosing destination for pediatric patients. We found that just under half of patients were documented as closest facility, and over one-third as patient/family choice. Significant differences in destination reasons were noted for rural versus urban counties. This study can help those currently developing pediatric EMS destination guidelines by revealing a high proportion of patient/family choice and identifying conditions with high proportions of destination reasons other than closest facility.

Objective: Pediatric care is now concentrated in urban specialty centers ("regionalization"), even for common conditions such as asthma. At the same time, rural emergency medical services (EMS) faces challenges related to adequate workforce staffing and financing. This statewide study describes how regionalization of pediatric inpatient care for asthma exacerbations affects EMS operations, particularly for rural agencies. Methods: This is a statewide cross-sectional study of EMS encounters for pediatric asthma in patients aged 2-18 years from 2011 to 2016 using Florida's EMS Tracking and Reporting System (EMSTARS) database. EMSTARS encounters were deterministically linked to Florida's Agency for Healthcare Administration (AHCA) database. We categorized AHCA hospital facilities that received included patients by whether they did or did not admit pediatric asthma patients during the study period ("admitting facility"). We used geospatial analysis to map the EMS agency's home county and the admitting facilities addresses. For each county in Florida, we calculated the average estimated EMS travel distance to the nearest admitting facility using a dasymetric mapping approach. Results: The study included a total of 11,226 EMS pediatric asthma encounters, of which 11,153 (99%) matched to an EMS home county. AHCA data was available for 3,812 (34%) patients. Most counties with distances to admitting facilities less than or equal to 15 miles were urban (31 of 39). For distances of 31-45 miles to an admitting facility, 7 of 8 of counties were rural, and for distances greater than 46 miles, all 4 counties were rural. Conclusions: In this statewide study in Florida, we found long average estimated EMS travel distances to admitting facilities for Florida's pediatric population in rural counties for pediatric asthma exacerbations. Those long distances have great implications for rural EMS operations, including pediatric destination decisions, transport times, and availability for others who call 9-1-1. Further research on bypass and secondary transport rates, and outcomes for asthma and other pediatric conditions are required to further characterize pediatric regionalization's impact on rural EMS.
